| Abstract(in English) | One-Time Password (OTP) method is a secure password-based authentication method by changing password in each session. We have already proposed a single OTP method usable by multi-authentication agents. In this paper, we evaluate the security of the proposed method. We show the proposed method can protect the secret information of user from not only unknown the opponents but also the agents and other users. And, the proposed method can protect the secret information of the agent from not only unknown the opponents but also the users and other agents. Additionally, the proposed method is secure against the known attacks, e.g. Man-In-the-Middle attack, replay attack, and Denial-of-Service attack. Therefore, our method is secure against the known attacks. |
